Q:

Testing the latest R&L Valve

I’ve been looking forward to testing out the R&L offering for sometime now.

So OK Guy’s, The test numbers are “IN!!!”

R&L has continued to improve their valve system. Randy sent me three different valve bodies, and the newest version of their valve stem. It is well machined and fairly conservative on air.

Here are the numbers in both my carbon fiber tank AND the standard AF tank, and shooting through a 7mm, or 27 5/8″ Barrel by TJ’s. Also set up by R&L.

This is a Semi custom R&L offering. The bushing supplied with the barrel are well fitted, and the finish and machine work of the barrel it’s self is exceptionally well done. The Barrel is nicely crowned, however, the end user needs to set the lede for his chosen himself.

The front bushing on this particular barrel is set up for its matched Shroud, in that the front bushing is threaded to match the base of the LDC. Between the threaded rear of the bushing/LDC, and the well thought out combo Muzzle alignment to shroud/ air stripper, very small Dia. passages are possible.

This really helps as small passages can often lead to clipping. This has been well taken care of. I was afraid at first the shroud was set up for .22 but a quick call to Randy at R&L confirmed that it was indeed a .257 Shroud. and NO It Didn’t Clip!!! I’m Stoked!

As many of you know, I cast my own bullets from a custom NOE mold that throws them out at 60 grains. This is a 20-1 lead tin mix, and is Very-Very accurate!!! Think 1/4″ out of a good barrel accurate 0n my 80 yard Home Range.

AF tank @ 3000 psi.

973 fps @ 126 fpe This is a HUGE performance increase above the Stock AF Condor valve, which was tested first. It ran a little over 800 fpe. In fact at 3200 it ran 830 for a fpe of 91.8.
That’s a 34 fpe increase from the valve alone folks! (Even at 3500 psi, the AF stock valve could only reach 850 fps).

Now for the good stuff!!!

In the CF bottle, set at 3700, the factory valve hit only 850 for a fpe of 96.28. It would seem that the AF valve had pretty much reached it’s limit of flow capacity.

This is with the supplied valve body and newest stem.

3000 psi in a factory bottle with 3000 psi, 973 fps for a fpe of 126. Not bad at all!

Now put this same valve in the cf bottle, and fill to 3700 psi, and it still responds.
It put the 60 gr. NOE Flat Point down range at 1037 fps for a total of 143.31 fpe.

I would say that this is a very respectable improvement over the factory offering. In fact, a Woo-Hoo Improvement!!! LOL!!!
What’s more, it is immediately available with a simple phone cal, visit to R&L’s web site, l or e-mail.

There something else coming along, that is even more exciting! Wish I could tell you all about it. But it is going to change bullet shooting quest for ALL involved.
Perhaps one of the players will chime in once every thing is finalized.

Oop’s! Did I hear someone ask, Yeah, that’s all great, but how did it shoot. could you hit the broad side of a barn with it? Well, yes you can. In fact, you can hit the screw heads holding the Barn Doors on their hinges.

First shots were two at a time, 80 yards, at 1″ circles. First two shots formed a overlapping horizontal 8. Moved on to the next target, same-same. Next same-same. Three targets, three locking horizontal 8’s. Not only that, they were all in exactly the same place on the targets! Extreme spread of group? How about well under .295″ Yep, under 1/4″ at 80 yards. I got cocky and shot a 10 shot group. Of course there was the always present flyer. And one only. You guessed it. It was the last shot! Grrrrr!!! Group size, still under 3/8″. Add in the flier,and it increased to just under 1/2″. I’ll Take It!

No wonder they don’t want Tofazfou shooting at the Extreme Bench rest!!!LOL Yeah-Yeah, I know-I know, it’s the safety thing. But Still—–The way these .257’s shoot—–I wouldn’t want to try an beat them!

I never tried the R&L valve with a stock spring. I just left the one in the gun I was already using. It is a 9.5lb that I got from Dyotat a while back. Like wise, the hammer is a bit heavier. As it is made of brass. A Talon member sent it to me several years ago, and i haven’t weighed it lately,
and I’m far too old to remember! 😆

I do know that the stock spring, or any spring can go into coil bind and actually slow things down. So a stronger spring is used to give the higher resistance, without it going into bind from being cranked all the way down.

a heavy hammer and spring can cause valve bounce of it is too much for the gun to handle at it’s setting. this caused the valve to open, the hammer to rebound, and strike the valve again. It causes higher use of air, more noise, and can cause the valve to open quicker, and snap shut too fast killing some of the energy.
I usually put an “O” ring behind the valve stem top hat to try and stop this bouncing. It usually works. It’s sorta a poor mans regulator. 😆

And that is why the testing is so important with these guns. They can be fantastic! But they need a bit of encouragement. LOL!!! 😉

I don’t do much tinkering myself on my air guns so its likely I’m not fully getting it. I thought dialing up the power wheel was pretty much just setting more spring preload tension. Having thought that…I thought the fact that the fps went way down at higher settings a heavier spring is not going to help (since it didn’t even like using all currently available). RL told me on the phone that a heavier hammer actually lowered velocities with his valve, so I had just ruled that out, at least with stock tank and fill pressure of 3000 psi. I did not specifically ask about a different spring so now I’ll have to check that out. How about opening up the stem a little more? What advantages might I see going to the .257 non-choked barrel? I love to hunt. Taking apart my air guns to improve them is not really as fun to me as others on this site so I really do appreciate the advise and shared knowledge. I’d rather ask more. Research more and only make changes that will be successful in relation to my goal for the gun. Your post was a bit of a cliff hanger….what else might you suggest? For now I will find a spring. Thanks.

Quote, ” I can see from the low power setting needed that it doesn’t want more hammer or spring, ”

I’m not sure I follow. How does the results of the power at a low setting tell you it can’t use more?

That’s the difference with the R&L valve stem compared to the stock one. Where the factory valve will top out, the R&L can keep responding t more spring, more hammer, and especially more air pressure. But it takes More spring pressure to over come higher bottle pressure, in order to take full advantage of it.

I have carried the R&L all the way to 4400 psi, and it continued to increase the fps. (this of course was with an after market 4500 psi CF Bottle on the gun NOT the factory bottle!).

This was with the new valve body, and new stem together. It does take both to make it work well with bullets.

Keep me informed on your progress. There is one more trick to try, “IF” your’s needs it.

We’ll see.

Knifemaker, I just got the rl extreme valve in my condor .25. I was a little disappointed today when I took it out for some chrony time. Everything else on the gun is stock. With the original valve I was able to get 907 fps from a 53 gn bullet. New valve got max of 930 with same bullet. So originally was close to 97 fpe and now almost 102 fpe. (actually 930 and some change in fps) That took some time to achieve and ended up with most power with it set around 4. I have assumed the rifle would benefit from a non choked barrel. Do you think the difference in our results is the choked stock barrel? Also it has rl’s one piece stem. I can see from the low power setting needed that it doesn’t want more hammer or spring, but what about more air flow through the stem. Maybe TT’s high power stem or the adjustable one? This is an old post so I hope you see it soon and can share your thoughts. I usually use a sam yang recluse for coyotes but this gun is so fun to shoot that I really want to get some more power out of it.

Man the accuaracy you guys are wringing out of your .257’s is nuts. good shooting.

could i benefit from a reg on a .22 condor ss, if so could you give me a explaination of how?? very intersted in this

I didn’t take pic’s. Just shot the hell out of it! R&L Should have pix’ soon! 😉

Are there any pics of the R&L .257 setup and details?

Man, Winter Blows doesn’t it! Nothing but damp wind here. Grrrrr! 👿
It was nice yesterday, lots of wind, but bearable. Shot probably 200-300 .257’s down range. Wind sure screwed with the groups though. But the .257 handles the wind so much better than pellets that all my pellet barrels are collecting dust! 😆

Hope you get the custom bullets Soon D. I’m anxious to hear how they do for you. I Love’m!

Sweet group there Knife! We need more slug technology and designs out there. So far, the sized-down .257 worked fine in the .25 TJ… then, the scope went south. :angrymob:

The weather, a defective Hawke Sidewinder and work have kept me from shooting the Dyotat .25 “dual-duty”. The pellets got dialed in with the latest group 5/16 inch, ctc at 40 yds, 5 shots, no bench. Got a replacement scope for free but right after the pellet profile got re-dialed-in, it started raining, or wind, or ice, or some combo.

Doug sent me a variety of slugs to test out and I’m going nuts waiting for a chance to get out and shoot, figured out for best accuracy. It’s higher on my to-do list than fixing the bedroom shower!***

The gun’s amazing; Doug’s work is the best. This is a new concept, two tanks set up for widely different ammo. I’ll post a review with pics. Might do that before the best slug accuracy details are worked out.

***Better post this before my wife walks in :mrgreen:

Thanks Knife. Can’t wait to try them out. I got the mods done to the valve I have now so gonna see how that goes. That is a great group at 80 yards. If my guns will shoot that good I will be super excited!!

quote Drumie:

I am excited about this. I am going to order one to play around with while I am still waiting for Dougs valve to get here. It is great for airgunning. The more people shooting these .257 the more we will learn about them.

Your’s are going in the mail this morning! Woo-Hoo!!! 😀

Knife

Man~! A barrel that can shoot .25 bullets, and Pellets! What could be better!!! :8:

a shame there aren’t more people making molds for the .25 as it sure would make life much easier. V. smith is making them, But Dayum!!! Expensive. 😯

You have some good bullets coming? How are the sized down .257’s doing?

I have several people asking me for my 60 grain bullets from the custom NOE mold that I decked.

In fact, shipping out a few hundred this morning. It is the only bullet I offer, as I don’t want to step on any toes. Especially RJ’s. He does a fine job, and is a pleasure to do business with.

How’s This? :8: It’s with the 21″ barrel. The new 27 5/8″ is even more accurate!

Well Knife, There are LOTS of reasons you don’t see more responses: Hoot’s likely passed out under a table or shooting chickens; I was working like a dog; Tof is probably shooting something. A bunch of guys are also distracted to “other” sites, etc. You know, the ones with lots of … p _ _ … pictures 😛

Thanks for the post! I believe you and I’m sure Doug and Tof can vouch for the TJ barrel’s performance. I got one in one of Doug’s builds, only in .25 cal. In fact, the slugs I’ll be testing out were .257 sized down. Doug’s brother was smacking a hardball at 100 yds with the slugs and Doug was hitting a golf ball at 100 yds with Kings, in the same barrel. If the air is right, the barrels are mighty fine performers. Post some pics, if you can.
